Britney Spears may be the ringmaster, but that doesn't mean there isn't room for another vocal powerhouse under the big top.

Brit's official blog announced today that Jordin Sparks is joining the second leg of the Circus tour, signing on just in time to hit all of the U.S. hot spots including New York, Los Angeles and two nights in Las Vegas.

Following in the footsteps of former Circus openers Ciara and the Pussycat Dolls, the 19-year-old American Idol champ could not be more thrilled about the pair-up, exclaiming: "Britney's show is incredible and for me to be a part of it is a great opportunity."

Sparks released her hit sophomore album, Battlefield, in late July and just wrapped up the North American leg of the Jonas Brothers world tour.
